HORSE-DETAGHER.

SPECIFICATION forming part of Letters Iatent No. 753,910, dated March 8, 1904.

Application filed October 28, 1903.

' the following is a specification.

My invention relates to new and useful improvements in horse-detachers; and its object is to provide a device of this character es-. pecially adapted for use in connection with two-horse teams and which can be operated the vehicle.

from the seat of a vehicle and will simultaneously detach the traces of the harness from the swingletree. I

With the above and other objects in view the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of. my invention, and in which- 7 Figure 1 is a plan view of a doubletree having my improved detaoher thereon, and Fig. 2 is a bottom plan viewthereof with the whiffletree removed and with the operatinglever partly broken away.

Referring to the figures by numerals of reference, 1 is a whiffietree having swingletrees 2 pivoted thereon at. the ends thereof. The pivoted pins 3 of the swingletrees also serve as pivots for oentrally-fulcrumed levers 4, and one end of each lever is connected by means of rods 5 with the ends of a T-shaped operating-lever 6, which is fulcrumed upon the whiflietree and the arm 7 of which is provided with an operating-arm 8, which is adapted to extend backward to the seat upon Each end of each swingletree is inclosed by a casing 9, having an L-shaped extension 10 at the end thereof, and slidably mounted within this extension and within the casing is a plunger 11,which is held normally projected into the extension 10 by means of a coiled spring 12. This spring bears at op- 1 posite ends upon the adjacent end of the swingletree and upon an ear 13, which extends from the rod and is slidably mounted in aslot 14, formed in the casing 9. A pin 15 is arranged upon the ear 13 and projects intoa Serial No. 178,863; (No model.)

slot 16, arranged longitudinally in a rod 17 which is pivoted to the lever 4, located under and the traces-are then inserted into the extensions 10 and the ears released, so as to permit the plungers to spring into engagement with the traces. The backward movement of the plungers is permitted in view of thefactthat the pins 15 are mounted in the slots 16. When it is desired to detach the traces from the swingletrees, the-rod 8 is pressed forward so as to swing the operating-lever 6 upon its fulcrum and draw upon levers 4 through the rods 5. These levers will pull the bars 17, connected thereto, in opposite directions and will move the ears 13 therewith and causethe plungers 11 to be simultaneously retracted from the extensions. As soon as the operating-lever 6 is released the several springs 12 will return all'of the parts to their normal positions. It will be seen that the device is extremely simple and inexpensive in construction and affords efi'icient means for detaching horses, thereby rendering the device extremely desirable where spirited horses are employed.

In the foregoing description I have shown the preferred form of my invention; but Ido not limit myself. thereto, as-I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described .the invention,what is claimed as new is 1. In a device of the character described, the combination with a whiffletree having a swingletree thereon, and an operating-lever fulcrumed upon the whiflietree; of a lever interposed between the whifiietree and-the swingletree and projecting from 'opposite sides thereof, spring pressed plungers slidably mounted within the ends of the swingletree, trace-receiving extensions normally engaged by the plungers, rods connecting the ends of the lever with the plungers, and a rigid connection between said lever and the operatlng-lever.

2. In a device of the character described,

the combination with a whifl'letree having a swingletree pivoted thereon,and an operatinglever fulcrumed upon the whiffietree; of a lever interposed between the whiffletree and the swingletree, a rod connecting the two levers, spring-pressed plungers slidablymounted in the ends of the swingletree, trace-receiving extensions normally engaged by the plungers, ears extending from the plungers, and rods connecting the ears with the projecting ends of the interposed lever.

3. In a device of the character described, the combination with a whiifletree having an operating-lever fulcrumed thereon, and a swingletree pivoted upon the whiflietree; of a transversely-extending lever interposed between the whifiletree and the swingletree, a rod connecting said levers, a casing upon each end of the swingletree, an angular extension thereto, a spring-pressed plunger slidably mounted in each casing and normally engaging the extension, an ear upon each plunger, a slotted rod connected to each ear and to the transversely-extending lever, and means for rotating the operating-lever.

4. In a device of the character described, the combination with a whiflietree having swingletrees pivoted thereon, and an operatinglever interposed between the swingletrees; of transversely-extending levers mounted between the whifiietree and the swingletrees, casings upon the ends of the swingletrees, angular trace receiving extensions thereon, spring pressed plungers slidably mounted within the casings and normally engaging the extensions, ears upon the plungers, slotted rods connected to the ears and the transverselyextending levers, and rods connecting said levers with the operating-lever.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN PEARSON.
